Many artists are forgotten after they die, and some before they die. The Abstract Expressionist painter Theodoros Stamos (1922-97) is remembered, but not so much for his artwork. Rather, Stamos is best known for his role in the epic lawsuit brought by the heirs of painter Mark Rothko against the people who were supposed to protect Rothko’s legacy. (Hint: Stamos was one of Rothko’s estate executors.)
